on a wheel, and is quickly and easily re.

moved therefrom and taken apart.

A further object is to provide such a rim adapted to be made in sections 4and having means for locking said rim on the wheel with ordinary locking devices. l

More particularlyv it is iny object to pro- 'vide a rim which can be made in sections and when the casing is placed there. n can be locked on a wheel by means of a single j continuous-band and ordinary locking lugs.

A/further object is to provide'in such an automobile rim continuous iange members which are detachable and adapted when standing in different positions to fit either clencher tires -or the ordinary straight side tires.

My invention consists in the construction,

arrangement and combination of 4the various parts ofthe device whereby the objects contemplated are attained as hereinafter more full set forth, pointed out-in my claim and il ustrated inthe accompanying drawings, in which 2' l Figure 1 shows a Wheel equipped with an automobile -rim embodying my invention.

the outer surface ofthe felly l() isan annular protecti g member 11, having at onel edge an outwardly,inclined flange 12.

My .improved rim is made in two or more sections, Aeach of which comprises a flat member 13 having at'its side edgesoutwardly extending anfres 1%. rings or angevmember's. 15 `adapted to rest I provide continuous on the outer surface of the rim sections 13, as shown inl Figs. 2 and 3, and engage 'and The lflanges or rings 15.. are

faces 16 on one side, and with concave surfaces 17 on the other side to lit respectivelyflat edged tires or clencher tires.

ItA will be seen that by placing the. members 15 in one position with their"V concave .l

faces inwardly, as shown in Fig.' 2', therim is adapted for use with clencher tiresjwhile@ by reversing the'positionA of the members 15, as. shown in Fig. 3, my rim maybe used with l Hat sided tires.

On the lower surface of the 13, near one side thereof, is a downwardly' projecting member 18 having. va vertical sur-f face or shoulder 19 and an oute'rbeveled surfaceQOa, as clearly shownin Figs@ and I 3. The beveled'shoulderisadaptedfto reist." on .the outwardly inclined flange 12,'- "as` shown in Fig.12.= -The members., ,15.ar'e' placed on the' tire, the .sections of'my improved rim 13- are placed togetherend to"'fend.,l. A gconf.

tinuous Hat annular ring 20 is inserted ,fromv fao the side-opposite themernher .1S- until it ferr4 Vgages the shoulder. The'annularfringhas near its outer edge 'an. inwardly;extend# 'ing memberl 21, :havingan inner-vorticity shoulder 22, Vand an outerbeveledfsurface- 23. 'lfhel tire is inflated, and,fthe;}pressure w-ill-v be radially inward, .whereby A."tlie'f partsv of the rim are held'together iiifproper' Vposi-1 tion by friction. The tire andrim are-Ithelfj placed on thev wheell upon.- which :the ."Sho'ulj der 22 engages theside 4edge of thee-.member 11 opposite the flange-12.'

' For. securing'. the rim in position onfthe .Side of the', `feuyio nail-airingpatwaraiy inclined beveled s portionsl- 25 Aadapted v.to engage respectively the inner. surfacesggof .the

lflange' 12v and the 'inclined portion 23;

' 1A bolt 26 kis extended-through 'therhjody l installed, as hereinbefore described, Will prevent any lateral sliding of the rim. many of the bolts 2G and lugs 2i may be employed` as desired; l

YThe annular ring'QO is provided with a slot :28 Aextending from its side edge opposite the member 2l inwardly to a sullicient distance to lreceive the valve of the inner tube. One of the members 13 may be provided with a plate to fit into the slot 28 having a curved inner end to tit the valve stem. A lug 29,1nay be formed or placed on the inner surface of the annular ring "20 to engage a suitable groove in the member ll, to prevent circumferential creeping on theannular ring.

In Fig. 7, I have shovvn a slightly modified form of my invention, in which the ring 20 is provided with a downwardly eX- tending portion having an outer` beveled surface 30. The parts are assembled and C011-, structed similarly to those already described,

except that a special lug is provided having a body portion 31 through which the bolt 26 is extended, and has at its upper end the inn 'Wardly inclined Wedge member 22, the upper beveled surface of which engages and coacts with the beveled surface 30. It will thus be seen that the. member 2O is slightly spaced from the member 11. The rim, hoW ever, is held von and supported in the same Way against lateral movement.

'My improved automobile rim isunusually inexpensive to manufacture, and I believe it to have very great advantages, in that no expensive or complicated locking means are mais?? 'necessary for connecting the adjacent ends of the rim sections 13.

rThe rim can be assembled With 'the member :20 and with the tire thereon, and may be quickly and easily slid on the Wheel as assembled, when the form used in Fig. T is used. Then either form is employed, the member 2O is inserted laterally before the rim has been placed on the wheel.

I appreciate the fact that slight changes may be made in the arrangement and construction of the parts of my demountable rim, as for instance in the construction shown in F ig. 7, as compared with the construction shovvn in Fig. 2, and I intend by my present application to cover any such changes in construction and arrangement as may be included Within the scope of my appended claim.

I claim as my invention.

n a demountable rim, a rim having ends adapted to be adjacent to each other toform a1 continuous rim, continuous side rings for preventing outward expansion of the rim, a continuous band or ring adapted to engage the inner surface of said rim, said rim havingl a shoulder adapted to enlfzlfage one edge of said band, said band havi g at one edge a portion adapted to be engaged by a locking lug.
